First Day Hike

It was a cold January 1 in our area of Maryland and my husband was just getting over a cold --- he didn’t want to hike. So I took a very short hike from a two lane road near us down to the Little Patuxent River. I want to try out my new monopod/hiking pole. It turned out to be a good idea since I managed to unscrew the bottom section completely!

All the leaves were brown and brittle. The sycamore leaves were still largely intact and quite large from the trees growing along the river.

I was not fast enough to photograph the great blue heron that was evidently fishing in the river when I arrived.  There were some deer that were on the opposite bank - white tails flashing by the time I saw them.

The places where the water was still enough were still frozen from the previous night’s temperature drop into the 20s.

I looked for shelf fungus on the downed logs but only saw tiny ones but this moss with sporophytes add some color to the otherwise drab colors of winter.

On the way home I stopped at the storm water pond in our neighborhood.

The stumps from a visit from a beaver a few years ago were still visible near the short - and punctuated the ice at the pond’s edge.

And a surprise from my daughter in Tucson - they had snow on January 1! She sent the pictures below.

Gleanings of the Week Ending January 3, 2015

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

2014 in Numbers: Huge Valuations, Shocking Security Stats, and a Big Climate Deal - Factoids for the year. The last one was the one that caught my attention the most 4.4 zettabytes = all digital information in the world….and it is growing by 40% per year!

2014: An amazing year in space exploration - Philae, Orion, SpaceX Falcon 9, and Mar Rover Opportunity setting off-Earth, off-road distance record.

2014 in Materials: Rhubarb Batteries, the Gigafactory, and Printing Body Parts - It’s hard to keep up with all the innovations. How fast can any of these really get to market and be affordable?

Researchers create method that recovers high value metals for industries while protecting the environment - A step in the right direction. Hopefully the metals recovered will be valuable enough to drive the technology from the lab to application.

The Year in Pathogens - Ebola tops this list from The Scientist.

2014 in Computing: Breakthroughs in Artificial Intelligence - Seeing the aggregate for the year….2014 was quite a year for AI in a number of areas.

2014 in Energy: The Year in Energy and Climate Change - Increased urgency of warnings….only slow progress. Frustrating.

Young entrepreneurs innovate in green energy with an in situ organic waste digester - Kudos to the young Mexican entrepreneurs….and the company that is implementing their innovation.

American cities are many times brighter at night than German counterparts - The US could learn from German….and help us all see more stars in the sky too.

Social Media Sites Offer a Nice Sampling of Winter Scenery in Parks - Winter brings a different perspective.

Coursera - January 2015

The beginning of January is the lull period for Coursera courses just as it is winter break/between semesters for the universities that provide the content. I did two on-demand courses during the lull. I’ve finished all the videos for Introduction to Sustainable Development from Columbia University and am enjoying the first modules of the Astrobiology course from the University of Edinburgh.

The Sustainable Development course more about ‘why’ we need to do it rather than ‘how.’ It meshed well with the course from National Geographic about Water and the US Food System course from Johns Hopkins earlier this year. It is almost overwhelming how the big issues of our time are so interrelated.

The Astrobiology course also links well with other courses: The cosmology section of Philosophy and the Sciences (also from University of Edinburgh), Origins (from University of Copenhagen) and the Exoplanets course (from University of Geneva) that I finished last summer.  Having some of the same evidence discussed from a slightly different perspective deepens my overall understanding.

I struggle a little with the accented English of the lecturers in the Recovering the Humankind’s Past and Saving the Universal Heritage from Sapienza University of Rome…but I am still filling in some gaps in my knowledge.  It too links to some other courses from earlier this year - particularly The Art and Archaeology of Ancient Nubia from Emory University and Archaeology’s Dirty Little Secrets from Brown University.

Two new courses will start in January. Both are quite different that the courses I have taken recently….and are from universities new to my Coursera experience.
